### COMMENT AS NEEDED ###

# Check if requirements.txt exists before copying
|

# Using glob pattern so that build does not fail if requirements.txt does not exist
|
|
COPY requirements.txt /requirements.txt
|
|
|
|
### DEFAULT BOOTSTRAP BUILD CODE, RUN LOCALLY TO GENERATE requirements.txt ###
|
|
# If requirements.txt exists and not empty, install the listed packages
|
|
# If it doesn't exist or is empty, print a message and skip the installation
|
|
